Description

Technical Field

[0001] This utility model relates to the technical field of inflatable equipment, specifically to an inflator for a tent or air mattress. Background Technology

[0002] In outdoor camping and home leisure scenarios, tents and air mattresses are commonly used equipment, and their inflation efficiency and ease of use directly affect the user experience. Currently, most tent or air mattress inflators on the market only have basic inflation functions and lack dedicated deflation and pressure relief designs, resulting in significant limitations: Firstly, deflation is cumbersome. Existing inflators require unscrewing the main air hose to release air, and depressurization requires a dedicated pressure relief valve. This process is time-consuming, laborious, and costly, especially inconvenient for emergency outdoor storage. Secondly, repeated disassembly and reassembly can lead to component wear. The threaded connection between the inflator and the mounting base gradually wears down during repeated disassembly and reassembly, reducing sealing performance and leading to leaks after long-term use, thus shortening the lifespan of the tent or air mattress. Furthermore, some inflators lack pressure control functions. If the inflation device pressure is too high or the user operates improperly, the internal pressure of the tent / air mattress may exceed its bearing capacity, causing fabric rupture, structural damage, and other risks, further affecting the safety and reliability of the equipment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an inflation nozzle for a tent or air mattress, which addresses the above-mentioned shortcomings of the prior art.

[0004] To achieve its purpose, this utility model adopts the following technical solution: An inflation nozzle for a tent or air mattress includes an inflation tube with openings at both ends and a deflation structure located inside the inflation tube. The lower end of the inflation tube is externally threaded to a mounting base on the tent or air mattress, and the upper end of the inflation tube is externally threaded to an air nozzle cap. An insertion port is provided inside the inflation tube. The deflation structure includes a connecting rod, a baffle plate fixed to the bottom of the connecting rod, and a nut threaded to the top of the connecting rod. The connecting rod passes through the insertion port, and a flexible plug is sleeved on the connecting rod inside the baffle plate. The flexible plug can fit against the bottom end of the inflation tube. The insertion port has sliding grooves on both sides, and sliders are provided on both sides of the connecting rod. The sliders are slidably installed in the sliding grooves. A spring abuts against the nut and the insertion port.

[0005] Preferably, the groove gradually increases in size from the top to the bottom.

[0006] Preferably, the inflation tube has an elongated hole inside, and the elongated hole has a pressure relief structure that can move up and down. The upper and lower ends of the inflation tube are respectively provided with a first pressure relief port and a second pressure relief port that communicate with the elongated hole. During the inflation phase, the pressure relief mechanism blocks the opening connecting the second pressure relief port and the elongated hole. When the pressure reaches a certain level, air enters the pressure relief mechanism through the second pressure relief port and rises.

[0007] Preferably, the pressure relief structure includes a screw, a spring, and a plug. The screw is threaded to the upper end of the elongated hole, the plug is located at the bottom of the elongated hole, one end of the spring is sleeved on the top of the plug, and the other end abuts against the bottom of the screw.

[0008] Preferably, the inflation nozzle further includes a base shell with an outer edge, on which a locking sleeve is threadedly connected.

[0009] The beneficial effects of this utility model are: This utility model achieves an integrated "inflation-depressurization-deflation" function through optimized structural design: (1) Convenient deflation without disassembly: By setting a deflation structure consisting of a connecting rod, flexible plug, slider, groove and spring inside the inflation tube, the flexible plug is tightly attached to the bottom port of the inflation tube by the pre-tightening force of the spring to ensure a seal. When deflation, the flexible plug can be disengaged from the port by pressing the nut and adjusting the position of the connecting rod. The gas can be quickly discharged through the openings at both ends of the inflation tube without disassembling the air nozzle cover or installing the base. The operation is convenient and avoids thread wear, thus extending the service life of the components.

[0010] (2) Automatic pressure relief protection to improve safety: The long hole inside the inflation tube works with the pressure relief structure to achieve automatic pressure control; during the inflation stage, the plug blocks the second pressure relief port under the action of the spring to ensure efficient gas filling; when the internal pressure of the tent / air mattress reaches the set threshold, the gas pushes the plug up through the second pressure relief port, so that the gas is discharged from the first pressure relief port through the long hole, avoiding excessive pressure that could damage the equipment, and adapting to the pressure bearing requirements of tents / air mattresses of different materials.

[0011] (3) Stable sealing and firm installation: The lower end of the inflation tube is connected to the mounting base and the upper end is connected to the air nozzle cover by threads. Combined with the sealing effect of the flexible plug, it effectively prevents air leakage after inflation. At the same time, the combination design of the base shell with the outer edge and the locking sleeve can further strengthen the connection between the air nozzle and the tent / air mattress, avoid the air nozzle from loosening due to vibration and pulling during use, and improve the overall structural stability.

Detailed Implementation

[0015] The following are specific embodiments of the present invention described in conjunction with the accompanying drawings, further illustrating the technical solution of the present invention. However, the present invention is not limited to these embodiments. Specific details such as particular configurations and components are provided in the following description merely to aid in a comprehensive understanding of the embodiments of the present invention. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0016] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0017] like Figure 1-4 The image shows an inflation nozzle for a tent or air mattress provided in this embodiment, including an inflation tube 1 with openings at both ends and a deflation structure located inside the inflation tube 1. The lower end of the inflation tube 1 is externally threaded to a mounting base on the tent or air mattress, and the upper end of the inflation tube is externally threaded to an air nozzle cap 2. An insertion port 101 is provided inside the inflation tube 1. The deflation structure includes a connecting rod 3, a baffle 4 fixed to the bottom end of the connecting rod 3, and a nut 5 threaded to the top end of the connecting rod. The connecting rod 3 passes through the insertion port 101, and a flexible plug 6 is sleeved on the connecting rod 3 inside the baffle 4. The flexible plug 6 can fit against the bottom end of the inflation tube 1. Sliding grooves 1011 are provided on both sides inside the insertion port 101, and sliders 301 are provided on both sides of the connecting rod 3. The sliders 301 are slidably installed in the sliding grooves 1011, and the sliding grooves 1011 gradually increase in size from the top end to the bottom end. A spring 7 abuts against the nut 5 and the insertion port 101.

[0018] When deflation is needed, press the nut 5 clockwise to further compress the spring 7, causing the connecting rod 3 to move downwards as a whole, so that the flexible plug 6 disengages from the bottom port of the inflation tube 1; the gas inside the tent / air mattress enters the inflation tube 1 through the bottom port of the inflation tube 1, and then exits from the upper opening of the inflation tube 1; after deflation is completed, press and tighten the nut 5 again, the spring 7 returns to its original shape, causing the connecting rod 3 to move upwards, and the flexible plug 6 re-fits the port, restoring the seal.

[0019] Furthermore, the inflation tube 1 has an elongated hole 102 inside, and a pressure relief structure that can move up and down is provided inside the elongated hole 102. The upper and lower ends of the inflation tube 1 are respectively provided with a first pressure relief port 103 and a second pressure relief port 104 that communicate with the elongated hole 102. The pressure relief structure includes a screw 8, a spring 7 and a plug 9. The screw 8 is threadedly connected to the upper end of the elongated hole 102, the plug 9 is located at the bottom of the elongated hole 102, one end of the spring 7 is sleeved on the top of the plug 9, and the other end abuts against the bottom of the screw 8.

[0020] During inflation, external gas enters through the upper opening of the inflation tube 1 and fills the tent / air mattress through the lower port of the inflation tube 1. As the internal pressure increases, when the pressure exceeds the pressure of the spring 7 on the plug 9, the gas pushes the plug 9 upward through the second pressure relief port 104, causing the plug 9 to move upward along the elongated hole 102, further compressing the spring 7. At this time, the gas in the elongated hole 102 is discharged to the outside through the first pressure relief port 103, achieving automatic pressure relief. When the internal pressure of the tent / air mattress drops below the pressure of the spring 7, the plug 9 moves downward under the action of the spring 7, re-sealing the second pressure relief port 104, stopping the pressure relief. To adjust the pressure relief, simply turn the screw 8: turning the screw 8 clockwise increases the compression of the spring 7, raising the pressure relief threshold; turning the screw 8 counterclockwise decreases the compression of the spring 7, lowering the pressure relief threshold.

[0021] Furthermore, the inflation nozzle also includes a base shell 10 with an outer edge, and a locking sleeve 11 is threaded onto the base shell 10. The locking sleeve 11 is a ring nut with an internal thread on its inner side, which mates with the external thread on the outer side of the base shell 10. During installation, first, place the base shell 10 on the inflation tube 1 near the mounting base, so that the outer edge of the base shell 10 fits against the surface of the tent / air mattress. Then, turn the locking sleeve 11 clockwise until the bottom end of the locking sleeve 11 presses firmly against the surface of the tent / air mattress, further reinforcing the connection between the inflation nozzle and the tent / air mattress and preventing the inflation tube 1 from shaking or loosening after inflation.
